Current lab members

Lei Ma in the Zhong Lab

Lei Ma (malei AT ohsu.edu)
Ph.D., Peking University

Lei joined the Zhong lab in September 2017 as a postdoctoral fellow. He earned his Ph.D. at the School of Life Science, Peking University, where his graduate studies focused on the function of sleep. Lei found that REM sleep can selectively prune or strengthen certain learning pathways related to new synapse formation. He plans to take advantage of in vivo 2-photon lifetime imaging and the newly improved PKA sensor to study how PKA may contribute to different types of learning. Outside of work, Lei enjoys playing badminton and swimming.

Crystian Massengill in the Mao Lab

Crystian Massengill (massengi AT ohsu.edu)
B.S., Muhlenberg College

Crystian joined the Mao and Zhong labs as a research assistant in 2018 after graduating with dual degrees in Neuroscience and Religion Studies from Muhlenberg College. He is fundamentally interested in understanding the neural correlates of phenomenological experiences, and by utilizing two-photon imaging in conjunction with techniques in molecular biology, he continues an investigation into the development of sensors and manipulators for neuromodulatory activity with single-cell resolution. Outside of the lab, Crystian is an avid writer, pianist, and weightlifter, and he most enjoys relaxing with a cup of coffee and his kitten Artemis.

Maozhen Qin in the Mao and Zhong Labs

Maozhen Qin (qinm AT ohsu.edu)
Bachelor in Nursing

Maozhen obtained a bachelor's degree in nursing in China and has been working as a research assistant since 2008. She joined the Mao and Zhong labs in 2011 where she quickly became the "go-to" person for genotyping, culturing slices, performing animal surgeries, and maintaining the inventory of lab supplies. She became lab manager in 2014. Outside of work, Maozhen enjoys camping and hiking.

Weihong Xiong in the Zhong Lab

Weihong Xiong (xiongw AT ohsu.edu)
Ph.D., Peking University

Weihong is a staff scientist who joined the lab in March 2015. He has extensive experience in electrophysiology and also excels in molecular biology and microscopy. Weihong uses 2-photon microscopy in slice preparation combined with any other applicable methods to examine protein dynamics and synaptic heterogeneity in neurons.
